1. * These parameters are active only when two controllers are connected to a single display ACP01.
2. ** These parameters are active only when the system operates with input 0-10Vdc.
3.2 Commissioning
Checks to be done at first lighting, and after all maintenance operations that invol-
B
ved disconnection from the systems or work on safety devices or parts of the
boiler:
Before lighting the boiler
•
Open any on-off valves between the boiler and the systems.
•
Check the tightness of the gas system, proceeding with caution and using a soap and water solution to detect any
leaks in connections.
•
Check correct prefilling of the expansion tank (ref. sec. 4.4).
•
Fill the water system and make sure all air contained in the boiler and the system has been vented, by opening the
air vent valve on the boiler and any vent valves on the system.
•
Fill the condensate trap and check correct connection of the condensate elimination system.
•
Make sure there are no water leaks in the system, DHW circuits, connections or boiler.
•
Check correct connection of the electrical system and efficiency of the earthing system
•
Make sure the gas pressure value for heating is that required.
•
Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler
IF THE ABOVE INSTRUCTIONS ARE NOT OBSERVED THERE MAY BE RISK
B
OF SUFFOCATION OR POISONING DUE TO GAS OR FUMES ESCAPING;
DANGER OF FIRE OR EXPLOSION. ALSO, THERE MAY BE A RISK OF ELEC-
TRIC SHOCK OR FLOODING THE ROOM.
Checks during operation
•
Turn the unit on as described in .
•
Make sure the fuel circuit and water systems are tight.
•
Check the efficiency of the flue and air-fume ducts while the boiler is working.
•
Check the correct tightness and functionality of the condensate elimination system and trap.
•
Make sure the water is circulating properly between the boiler and the systems.
•
Make sure the gas valve modulates correctly in the heating and domestic hot water production phases.
